Growing demand for ethanol has spurred the expansion of local fuel processing terminals and train tracks, leading to noise complaints from Woodbridge residents, according to a report on MyCentralJersey.com.

The report said from Sewaren to Carteret, homeowners said they measure the growth of train traffic by the nights of interrupted sleep and the cracks in the walls of their homes. Resident complaints fall into three general categories: the shriek of the horn to warn of a train approaching an intersection, the racket caused by train cars crashing together as they couple and uncouple and a third is the roar of engines when trains are parked idling in residential areas.
